Findings support that DA does not simply encode spontaneous movement, but acts as a pathway-specific gain controller that dynamically tunes the transformation of glutamatergic input into SPN output to bias locomotor-state transitions in vivo.

Flexible behavior depends on neural mechanisms that integrate memory with ongoing motivational demands. Studies have revealed dopamine (DA) to have an essential role in mediating memory, behavioral flexibility, and decision-making, yet the dopaminergic contributions within prefrontal-hippocampal circuits remain poorly...

Dopaminergic signaling in the nucleus accumbens (NAc) is central to reward-based learning, but its relationship to brain-wide hemodynamics remains unclear. Using concurrent fMRI and dopamine photometry in awake, behaving mice, we reveal that associative learning induces a gradual temporal shift in NAc blood oxygenation...

Abstract Background Behavioral flexibility—the ability to update actions when contingencies change—is essential for survival and depends heavily on basal ganglia circuitry. Although the basal ganglia integrate contextual, reward, and motor-planning signals to enable adaptive control, most mechanistic work on behavioral...

Everyday decisions depend on associations between sensory stimuli, actions, and outcomes. The striatum supports these sensorimotor associations through dopamine-dependent plasticity. Recent work has characterized a local striatal microcircuit in which cholinergic interneurons (CINs) modulate dopamine release via activa...
